In a generator, you reverse the process: You move a magnet past the armature to create electric current in the coil. A primary coil of perhaps 200 turns of thick wire wrapped around one leg of the U.A secondary coil of perhaps 20,000 turns of very thin wire wrapped around the primary coil. The secondary coil, having 100 times more turns than the primary coil, amplifies this voltage to approximately 20,000 volts, and this voltage feeds to the spark plug.
A secondary coil of approximately 20,000 turns with very thin wire wrapped around the primary coil. An ignition coil is an induction coil in an automotive ignition system that converts a low battery voltage into the thousands of volts needed to create an electric spark in the spark plugs to ignite the fuel. On the other hand, if the electric coil is physically intact, it may still work fine after a repair, so have tools ready to rewind the coil.
A secondary coil of perhaps 20,000 turns of very thin wire wrapped around the primary coil. An ignition coil is an induction coil in an automobile’s ignition system that transforms the battery’s low voltage to the thousands of volts needed to create an electric spark in the spark plugs to ignite the fuel. On the other hand, if the electrical coil is physically intact, it may still work well after a repair so get your tools ready to rewind the coil.
Electrical currents run through the ignition coil and transmit electricity to the spark plug. If you observe a spark jumping between the tips of the spark plug gap, it means the chainsaw coil is good.

how does chainsaw coil work Related Question:
How do I know if my chainsaw coil is bad?
If your multimeter displays a reading of zero, it is an indication that you must replace the coil of your chainsaw at once because it has short-circuited. If your multimeter displays a reading above the specified level it is an indication that you will also have to replace the coil of your chainsaw because it is open.
How does an ignition coil operate?
The basic principle of an ignition coil To produce the required high voltages, ignition coils make use of the relationships that exist between electricity and magnetism. When an electric current flows through an electrical conductor such as a coil of wire, it creates a magnetic field around the coil (Figure 2).
How do you test a chainsaw ignition coil?
Pull the start rope on the chainsaw and watch the end of the plug as you do. If you observe a spark jumping between the tips of the spark plug gap, it means the chainsaw coil is good. If there is no spark, it means the chainsaw coil will need to be replaced.
What is inside a chainsaw ignition coil?
A primary coil of perhaps 200 turns of thick wire wrapped around one leg of the U. A secondary coil of perhaps 20,000 turns of very thin wire wrapped around the primary coil. A simple electronic control unit that commonly goes by the name “electronic ignition” A pair of strong permanent magnets embedded in the flywheel.
What should the Ohms be on a coil?
You should have a resistance reading of at least 3-4.5 ohms. A bad coil will show a higher reading then 3-4.5. Next, place the red or black lead from the meter to the centre of the coil , and to either one of the terminals positive or negative. You want 9500-10000 Ohms, a little less is ok but no more.
How many ohms should a chainsaw coil have?
Some chainsaws have coils with their positive and negative terminals clearly marked with the + and – signs. However, some others come with two terminals with pins that are situated at the connectors. A chainsaw’s coil has an average resistance range of 0.4 – 2 ohms.
What would cause no spark from coil?
Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap.
How long do ignition coils last?
The ignition coil on your car is supposed to last around 100,000 miles or more. There are a number of factors that can lead to this part become damaged prematurely. Most of the newer cars on the market have a hard plastic cover that is designed to protect the coil from damage.
What is the gap between ignition coil and flywheel?
Replacing Ignition Coils or Armatures An ignition armature must be set at a precise distance from the flywheel. Your engine repair manual will provide the proper gap for your engine. Common armature gap ranges are . 006 – .
What tells the coil fire?
In order to make the ignition coil work, the battery is used as a low voltage source. ignition coil to pulse, and that helps each spark plug wire have the electricity it requires. The sparks that occur from the spark plugs will come from the power traveling down the wire, causing it to spark.
What wires go to the coil?
They usually required only three wires: the spark plug wire, the power wire and the ignition switch wire. Ignition coils of this type are usually a little larger than a soda can and are heavy because of the metal core and the field coil windings.
Which side of the coil does the condenser hook to?
The capacitor is connected to the positive terminal on the coil.
What sends spark to the coil?
The low voltage primary circuit operates at battery voltage (12 to 14.5 volts) and is responsible for generating the signal to fire the spark plug at the exact right time and sending that signal to the ignition coil.
How do I know if my coil has power?
Locate the positive or power wire attached to the engine coil. Check for power using a test light. If this wire has no power, then your ignition coil is not receiving current. You should check the wiring from your ignition switch to the coil for breaks in the wire and repair them.
Does a ignition coil have constant power?
Re: Coil has constant power Yes, the coil is always connected to the battery. It’s no more of a problem for the wires IN the coil than it is for the wire ON THE WAY to the coil, as long as there is no current flow.
